CPT® Code 93225

External electrocardiographic recording up to 48 hours by continuous rhythm recording and storage; recording (includes connection, recording, and disconnection)

The CPT® Code 93225 refers to the procedure of external electrocardiographic recording, which is conducted for a duration of up to 48 hours. This procedure involves continuous rhythm recording and storage of the heart's electrical activity while the patient engages in their normal daily activities. The device used for this monitoring is commonly known as a Holter monitor. During the procedure, electrodes or leads are affixed to the patient's chest, allowing for the collection of electrocardiographic (ECG) data. The patient is provided with instructions on how to properly use the monitor throughout the monitoring period. The Holter monitor continuously records the ECG waveforms, capturing the heart's rhythm and rate, as well as other important metrics such as ST segment analysis, heart rate variability, and T-wave alternans. The data collected is stored on a magnetic tape or a digitized medium for subsequent analysis. After the monitoring period concludes, the patient returns the device to the healthcare provider, where the recorded data is reviewed. A visual superimposition scanning technique is employed to create a comprehensive overview of the entire recording, allowing for the identification of various ECG waveforms and the extraction of selective rhythm strip samples. Following this analysis, a report is generated, which is then reviewed and interpreted by a physician or qualified healthcare professional to assess for any potential heart arrhythmias. It is important to note that while CPT® Code 93225 covers the recording aspect of the procedure, including the connection, recording, and disconnection of the device, other related codes such as 93224, 93226, and 93227 are designated for the complete procedure, analysis, and interpretation of the data, respectively.
